Is it enough to run MSE and Windows Defender for adequate protection?

« Other questions

I have installed Microsoft Security Essential, Windows Defender, and Windows Firewall, on my Windows 7 Home Basic 32-bit SP1 PC. I keep Windows Updates, and Virus and Spyware Definitions up to date. I have also installed a free version of Malwarebyte Anti-Exploit.

My questions are–

Whether my Internet Security and Computer Security arrangements are sufficient, or not?

Whether I need to make any addition, alteration in security arrangements?

Thank you.

“Whether my Internet Security and Computer Security arrangements are sufficient, or not?”

My view is that no, it isn’t. But there are some things to consider. All the security in the world can be made useless by being careless/making poor decisions (whether because of hastiness, ignorance or something else is irrelevant). You shouldn’t follow just any link, and you shouldn’t open attachments in email if it isn’t asked for (but keep in mind that even if you did ask for it, it could be that someone interfered [yes this could happen, rare as it might be] or maybe the person you asked to send [whatever], didn’t know it was malicious? They don’t run anti-virus or their software failed to detect it?). Equally important is that security is meant to be a many-layered thing. So yes, you do need anti-virus and also at least a firewall, but there are more steps you can make (including things like NoScript for Firefox – as long as you use it properly, anyway). Last i knew Microsoft Security Essentials did quite poor on detection rate (I seem to recall a rather disturbing reference – will see if I can find it after posting this[1]).

“Whether I need to make any addition, alteration in security arrangements?”

I think that depends on what your funds are and what you’re capable of implementing. I don’t think what you have is sufficient but again there is more to it than anti-virus and firewalling. One more thing I would recommend to you: daily backup. Whether you want redundant storage or not is another matter entirely (I would recommend it but many don’t do it – but many don’t backup, either). And no, redundant storage isn’t backup because if you make a mistake (edit a file, delete a file or something else) or malware (or a bug in software) corrupts a file (or does something to your system), then that is stored on the other disks, too. Yes, backups can also be affected by this but that’s why you should do this all together (and stay on top of security; keeping software up to date, for example).

[1] There seems to be either a server side or (I presume) a page error, so it tries to reload itself, and unless you have a way to stop it (Firefox should by default, for instance), it might be a problem for you. Anyway, this is one resource:

On the other hand, the following shows what might be a bit more encouraging (I don’t know though – I never did understand the reasoning behind Microsoft’s versioning system and so I don’t know what the latest version of MSE should be) – (there is a link for Microsoft Windows Defender). It should be noted though, that it seems not all tests were entered (so it compares 1 test of 12 with 11 not entered). What that means entirely I can’t say.
